Sure, make fun of it, but sails are not the same as kites.
With modern tech they might be able to make kites that are truly enormous, way bigger than the sails that are limited by the size of the mast. In addition, the kites can be raised into different winds than the ones at the surface.
It's like kitesurfing vs. windsurfing.
